(ANSA) - ROME, OCTOBER 26 - The timber felled in Trentino by the storm Vaia - which on October 29 2018, with rains and winds estimated at over 150 km / h, hit the alpine area of North East Italy - becomes a record.
In Rovereto, in the former Marangoni Meccanica area, the largest wooden building in Italy is taking shape, a symbol of rebirth: with its 9 floors by 29 meters, it is intended for social housing and is built 100% with the precious wood of trees fallen, thanks to the work of Pefc certified companies and members of the Solidarity Supply Chain, starting with the general contractor Ri-Legno.
To take stock two years after the Vaia storm is Pefc Italia, a guarantor of the certification of sustainable management of the forest heritage and its products which, immediately after the disaster, activated the Pefc Solidarity Chain, the only elogo system designed to support the areas affected by the storm. wood coming from the trees felled by Vaia which destroyed 42,500 hectares of forest causing over 9 million cubic meters of felled timber.
Today, despite the delay caused by the lockdown, almost half of this timber has been cleared: about 60% has been sold.
The project in Trentino, explains Pefc in a note, also includes another 5-storey building made with chipping wood.
Choosing the wood for the construction of the building has allowed to drastically reduce the climatic footprint of the work, because wood is a carbon deposit that is absorbed as Co2 through the photosynthesis of plants: in each cubic meter of timber the carbon corresponding to a0 is stored, 92 tons of Co2.
In addition, wood has a very low energy cost of production and disposal in relation to competing materials (concrete, metals), with an average saving of 0.7 tons of CO2 per cubic meter of wood used.
"The savings in emissions compared to traditional construction is of the order of 50-70%: what we are facing is the future of construction, a central element of the green deal in which Italy is called to participate to contribute to the objective of reducing emissions by 55% and contain the effects of the climate crisis, as indicated by the EU ", comments Francesco Dellagiacoma, newly elected president of Pefc Italy.
